Sinotech Ltd

Sinotech, are experts in coldforming components, have extensive experience in:

• net-shape coldforming
• near net-shape cold forming

Sinotech is a supplier of precision components within the Automotive, Fluid Power & General Engineering Industries.  We manufacture ISO9001:2008 quality assured precision machined components,which can be produced using a number of processes:-

• Single spindle Low Volume components
• Multi-Spindle High Volume production
• CNC turning utilising our multi axis technology.
• CNC milling utilising our 4 axis machining centres.
• Welded assemblies.

Sintech can supply precision machined components a vast range of materials including:-

• Copper
• Mild and Alloy Steels
• Titanium and exotic high temperature alloys
• Plastics
• Stainless Steels
• Brass
• Phosphor Bronze (Gun-metal)
• Aluminium

The molten metal needs to be injected into a mould under extreme pressure. This will result in a more homogeneous part, good surface finish and dimensional accuracy.  There would be a significant reduction in the requirement for post casting processing to get the required final configuration.

There are 5 main steps to the process cycle, these are:

• Clamping

 Two cleaned and lubricated die halves are clamped together within the production machine.

• Injection

Of molten metal (a predetermined volume) at high pressure into the die.

• Cooling

The solidification of the metal within the die cavity takes its final shape.

• Ejection

From the die cavity, of the casting.

• Trimming

Excess material from casting

Sintered Components Applications

Components produced by this route include the production of many complex components such as:

• Pressure plates
• gears
• cams
• sprockets
• levers
• ratchets
• bushing etc

These would be for use in the following industries:

• Automobile
• Hydraulic
• Agriculture

Sinotech are able to work with their customers and use their extensive knowledge and experience of metal forming & tool design.

To get to the optimised final tooling design, prototype components can be produced.

We are also able to supply Metal Stampings in a range of materials:-

• Steels, coated and uncoated
• Stainless Steels
• Aluminium
• Brass
